SHINGLE-STRIP MACHINE.

Patented Apr. 29, 1219.

To all 'whom it may concern:

Be it known that I, FREDERICK C. OVER- BURY, a citizen of the UnitedStates, and a resident of Hillsdale, in the county of ,5 Bergen andState of New Jersey, have invented certain new and useful Improvementsin shingle-Strip Machines, of which the following is a specification.

This invention relates to machines for making shingle strips, such asshown for example in Letters Patent No. 1,150,298, granted to me onAugust 17, 1915.

On the' accompanying drawings,-

Figure 1 represents a plan view of a mai chine embodying my invention.

Fig. 2 represents a longitudinal section through the same.

F ig. 3 represents the. stationary shear blade.

Fig. 4 illustrates the movable cutter for coperating with the stationaryblade.

Figs. 5 and 6 represent a blade and cutter for forming rectangular tabson the shingle strips.

Fig. 7 illustrates a sheet of roofing material and a severed shinglestrip.

The material, upon which the machine is intended to operate, consists ofan elongated sheet of roofing felt, e. felt or other equivalent fibrousmateri-al saturated or impregnated with asphalt or other waterproofingcompound, and coated on one or both faces with hard pitch or asphalt,such as will wthstand the action of the weather and will not bedeleteriously afl'ected by 'Solar heat. Pigment may be ncorporated inthe coating to impart the desired color thereto, or crushed slate orother mineral may be embedded in lthe coating, if desired, so asto 40provide a mineral facing. Such sheets are pfurnished in various widths,and, by means of the machine to be described, they are severedtransversely into shingle strips having spaced tabs or projections ofpredetermined Shape or configuration. When said strips are laid inhorizontal overlapping rows, the exposed tabs or projections simulate.or-present lthe appearance of shingles or tiles. Hence I term themshingle strips Referring now` to 'the drawings, the machine there shownis provided with a framework of any suitable character; for instance,

it may have the side frames 10, 11. 'Touri naled in proper bearings insaid frame are the cop'erating feed rolls 12, 13, which are gearedtogether by the gears 14, 15, to one of which -power is applied as willbe subscquentlyT explained. Beyond the feed rolls, with their surfacestangential to the periph- '60 ery of the roll 13, are a plate 16, and ashear block 17, the ends of which are secured to the side frames. i Asshown in Fig. 2, at the ends of the block 17 are downwardly projectingfianges 18 with elongated slots 19 through which bolts 20 or otherfastenings are passed into the side frame, whereby the block may beadjusted for a purpose to be described.

The shear block has a cutting edge transverse with relation to the sheeta, said edge being made up of the straight portions 21 and the indentedor concaV-ely curved portions 22. For coperation with said stationaryblade, there is a rotary cutter or Chopper 23 having a blade 24 whoseedge is complemental thereto. As shown in Fig. 4, said blade 24 has anedge comprising the straight portions 25 and the convexly curvedportions 26. Said blade is secured upon the rotary chopper or cutter bybolts 27. The outter is formed on or secured to a shaft 28 whose axis islocated above the plane of the table 16 and the shear block, so that,when it is rotated, the sheet is cut transversely into strips whoselength is equal to the width of Ihe sheet. The formation of thecopera-ting cutting members 'is such that the strips b are provided onboth edges with tabs or projections c and d which are complements ofeach other. 00 It is quite evident that tabs or projections of differentconfigurations may be produced by` varying the edges of the coperatingblades. For example, in Figs. 5 and 6, the stationary shear bladel 28has thev straight edges 29 and the rectangular indented edges 30. Thecutter, on the 'other hand, has a straight edge blade 31 which iscontinuous from end to end, and supplemental 'rectangular cutters 32secured upon the arms 33. In this case, the straight blade partiallysevers and partially tears the fabric transversely on a straight line,before the supplemental cutters cut the fabric, as

a result of which each severed shingle strip has one straight edge, andhas on the other edge rectangular tabs or projections. The

,indented edges 30 are usually narrow, so

that there is no difliculty in forming a straight cut across the'fabric, to form a straight upper edge on the shingle strip.

Any suitable power-transmitting mechanism mav be utilized for impartingmove;

ment to the herein described instrumental-f ties. For example, I mayemploy a'power' shaft 34 drivon by a belt 3 and pulley 36,' and having apinlon 37 lintermeshing with and driving a large gear 38 on the cutter wshaft 28. From said gear 38 power is transmitted' to the feed rolls byintermeshing llO idLer gears 39 and 40.

`I have found it convenient to employ an endless conveyer belt 41arranged to receive the several strips, as shown, in which case' `1t is,supported byl the rolls 42, 48. The

trunnions of the latter are 'journaled in adjustable bearings 431, onbrackets 44 pro jecting from the side frames, one of' Said trunnionshaving a Sprocket 45 driven by a chain 46 from a sprocket on theshaft34.

Having thus explained the nature of my said invention and described away ofl making and usingv the same, although without attempting to 'setforth all of the forms'in which it may` be made or all of the modesofits use, what I claim is: c

1. In` a machine for cutting non-metallic fllexible Sheet, r'oofing intoshingle strips, the combination with a frame and feeding rolls for theSheet, `lof a stationary shear block arranged tra'nsversely of thedirection of feed of the Sheet, and having a cutting edge comprising apl-unality of alternating straight portions and recessed portions, and arotary cutter having a continuous straight cutting blade to coperatewith the straight edge portions of the shear block to sever a Striptransversely from the Sheet, and having a plurality of spacedsupplemental blades complemental to the recessed edge portions of theShear block, to cut reces'ses in the vend of the Sheet.

A machine for .cutting non-metallic.

:heoaact flexible Sheet roofing into 'shingle strips, comprising rolls--for vfeeding the Sheet, and cutting devices consisting of a stationaryblock and a co-acting rotary cutter arranged transversely to the path ofthe Sheet for the waste pieces.

t 'A machine for cutting shingle stripsv transversely from a Sheet ofroofing mate` rial,' comprising feed rollstfor the sheet, a support forthe traveling Sheet, and cutting means arranged -transversely to thepath of the fsheet for Severing the Same, Said cutting means comprisinga stationary cutter and a rotary cutter, said 'Stationary cutter=--having a. series of equally spacedfirecesses7 and Said rotary cutterhaving a''series of progections to 'coperate With Saidirecesses,

andfv also having a straight edge blade for Severing the waste pieces atone end.

5.: In a machine of the class described, a rotary cutter having astraight edge cutting blade and spaced blades each provided with- Side:and end cutting edges.

In testimony whereof I have aflixed my signature. w
